You should ask about heart failure nurses. I am a cardiac nurse. Its a good idea to weigh yourself every day to see if you are fluid overloaded. If you put on weight it is an indication you may need diuretics. Yes, cardiac failure is scary, but you can manage it. I hope your echo is OK. Heart failure can cause elevated liver enzymes (ALT) because of congestion.
Please post if you have any questions about heart failure, I can try and answer.
